Please help. Problem with admin section after applying a redirect code in htaccess

[MountainTopAquatics]

ok i installed a sript using htaccess on my root directory.

the script is this:
RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.mypage.com/ [R,L]

What happens, is it allows me to acess my www.mypage.com/admin but it will not let me access my www.mypage.com/admin/......
it keeps redirecting me to main page. I can manually go into the file and turn it "off" but is there another way to do this?

Thanks in advance,
Ryan
